We also have new plasma TVs from Panasonic, in its ST60 (Smart Viera TC-P60ST60, $1,500) and flagship VT60 (Smart Viera TC-P65VT60, $3,400) series, as well as the company's flagship LCD TV (Smart Viera TC-L47WT60, $2,500). Among the new Samsung sets we're testing are two 3D-capable 60-inch TVs, one a plasma (PN60F5500AFXZA, $1,200) and the other an LCD/LED (UN60F7500AFXZA, $1,800).

For those on a tighter budget or who are looking for a set for another room of the house, we're also testing less expensive major-brand TVs, as well as models from secondary brands including Element, Haier, Insignia, and TCL.
